Abradable coatings for turbine engine shrouds are formed from biscuits formed of silicon-diffused powdered alloy compositions which are processed with an HF precursor to strip oxides from the coating during processing, the alloy blends comprising MCrAln alloys in which n is 0, 1 or more. A first memory cell includes a storage element, a first pass gate for selectively coupling a first line of the first port to the storage element, a second pass gate for selectively coupling a first line of the second port to the storage element, and a third pass gate for selectively coupling a first line of the third port to the storage element. A context is created with one or more threads. The low speed section generally includes a data bank configured to load one or more samples of an M-bit parallel input stream, and a multiplexer configured to produce the N-bit parallel data stream from the data bank.
